HARM type MEMS-based reed switch innovations address medical, automotive and other micro switching applications not previously possible

Abstract

Purpose

The purpose of this paper is to review the advancements in development of high aspect ratio microfabrication (HARM) type of micro-electro-mechanical systems (MEMS) reed switch sensors for much improved performance in a much more compact package.

Design/methodology/approach

The paper presents an in-depth review of a number of applications of HARM built MEMS reed switches and consultation with a manufacturer.

Findings

One manufacturer has introduced a totally new way to fabricate reed switches which brings numerous benefits such as reliability, higher voltage capability, lower contact resistance and other features in a new tiny package.

Practical implications

Manufacturers of devices needing the benefits of the reed switch concept but who need a much smaller and compact switch now have a new option to explore.

Originality/value

An expert insight into how to solve reed switching problems where space is at a premium.
